Somebody attacked a guy with a knife on the London subway.
Not scared enough about a piece of random street crime on the other side of the world yet?
Okay he also shouted scary Muslim stuff at the same time.
ZOMG! TERRORISM! THIS IS SO MUCH SCARIER NOW!
Congratulations, you just told angry, frustrated, egotistical potential maniacs all over the world that the best way to get noticed for once is to shout Muslim stuff when they do what they already would have done.
And gave the real terrorists what they want. Terror.
19 teenagers alone have been stabbed in London this year, there's been a surge in knife violence. But this one is getting worldwide news because the stabber had some dodgy Islamist pamphlets in his flat and shouted about Syria when he committed the crime.
Hook, line and sinker.
